Interesting to note, the green on the right side of the middle finger leaf is due it being underneath the the leaf to the right. I had added a dedicated UVB light to the grow.
 
If you start to research increasing mj potency, you'll find that UVB stimulates THC production. I added dedicated reptile lights instead of switching out my HPS for MH.

As for did it cause this, my guess is that it did with some combination of not having a particular nutrient to protect from the UVB rays.
